Community Circles as I envision them are built on the practice of people sitting together in “sacred circle,” which I believe is hard wired into the evolutionary process of all human cultures. One well known and powerful example is the council process practiced among Native American peoples. Another — one with which I am most familiar through my own background — is Torah study practiced among the Jewish people.
There are two relevant teachings in Perkei Avot / Teachings of the Ancestors, also translated as Ethics of the Fathers. It was part of the Mishna, which was based on an oral tradition dating back to roughly 500 BCE, and set down in written form in 220 CE.
“Let your house be a meeting place for people of wisdom; sit in the dust of their feet;
and drink in their words.”
Pirkei Avot, 1:4
“Who is wise?
The one who learns from every person.”
Pirkei Avot, 4:1
